Title:
  rtl8723be wifi unusable on lenovo ideapad y50-70

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The rtl8723be wifi adapter rarely connects to a network. When it does,
  it will be choppy (10% to 50% packet loss on a ping to the default
  gateway) and usually disconnect after a few minutes.

  Run with fwlps=0 ips=0 as options to the rtl8723be module, or testing
  https://github.com/lwfinger/rtlwifi_new/ didn't help.
